Purpose:
The purposes of this study were to: (1) describe the demographics and oral characteristics of deaf or blind children and adolescents receiving dental treatment at an institution for the deaf and blind (DBC); (2) compare this information to children and adolescents with no systemic disease or impairments attending a dental university clinic (UC); and (3) compare the oral characteristics between visually or auditorily impaired children and adolescents.
Methods:
The demographics and oral characteristics of 120 DBC patients and 119 UC patients and between 35 visually impaired and 85 auditorily impaired were compared using analysis of variance, chi-square, Fisher's exact, and multiple regression analyses.
Results:
When controlling for age, there was no statistically significant difference between the UC and the DBC patients regarding caries prevalence. A significantly higher proportion of DBC children had gingival inflammation. Visually impaired patients had a statistically higher level of dependence on caretakers and higher gingivitis and plaque scores than the auditorily impaired.
Conclusions:
Under oral health supervision, children and adolescents with or without hearing or visual impairment develop similar dental caries prevalence. Oral hygiene and resulting gingival inflammation are a challenge for the visually impaired and, to a lesser degree, the auditorily impaired.
